Ok, so I noticed the compass on my F5 isn't calibrated properly but somehow I can't seem to get it to calibrate properly using the relevant option in settings.
When following the instructions I get a 'calibration complete' about 1 in 5-10 times but the north is still off. I feel like an idiot for not getting this right so is there like a failsafe movie instruction on how to move my arm/watch? (Can it be done while on the wrist or do I really need to take it off, I never succeeded while having it on my wrist and only every now and then taking it off).
(And I have seen the manual and instructional animation on the watch, but somehow that doesn't connect in my head with actually moving my watch ;) )
